Faramir,
I find this thread intriguing. From my youth (which was in the 1960s and early 70s) I listened for elements of Elvishness in music, and was deeply affected when I found them. I have found it in places ranging from Tchaikovsky (parts of the ballets) to The Moody Blues (Tuesday Afternoon.). Only last month, I found some in PHil Wickham's worship music. One never quite knows when it might pop up.
That said, when the movies came out and people began publishing "Middle Earth"-style music, I had my checkbook ready. I have collected a fair amount and reviewed some of it here
online as well as trying to instill some
participation and later on some plain
discussion
Tolkien would have enjoyed some of the music that has come out, I think. And that is usually one of my measurements that I use. If the professor would have left the room, can we call it elvish?
But that might bring us back around to "Canonicity".
Interesting thread topic.
